Description

Technical Field

[0001] This invention relates to the field of razor devices, and more particularly to a razor blade marking device. Background Technology

[0002] A razor is a tool used for shaving, primarily sharpened by rubbing the blade with raw cowhide. There are two main types of tools: razors used for daily personal hygiene and cutting tools used in machining. Razors consist of a blade and a hoe-shaped handle. The handle is made of materials such as aluminum, stainless steel, copper, or plastic; the blade is made of stainless steel or carbon steel, and to ensure sharpness and durability, the cutting edge is often treated with a metal or chemical coating.

[0003] The razor blades have a double-sided structure with a through groove in the middle for positioning. Patent application number CN202323135474.0 discloses a marking device for manual razor blades, including a support, a marking table, a limiting plate, a longitudinal slide rail, a support plate, a first slider, a second cylinder, a transverse slide rail, a sliding plate, a laser marking machine, a second slider, a second connecting rod, a connecting vertical plate, a connecting horizontal plate, a first cylinder, and a first connecting rod. The marking table is located on the bottom surface of the support, the limiting plate is located on the surface of the marking table, the longitudinal slide rail is located on the upper surface of the support, and the support plate is located on the upper part of the longitudinal slide rail. The support plate and the longitudinal slide rail are connected by the first slider. The razor blades to be marked are arranged sequentially on the surface of the marking table, and the laser marking machine marks the blades on the surface of the marking table sequentially. However, this type of marking device requires placing the blades one by one on the table during marking and collecting them one by one after marking, which is inefficient.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a razor blade marking device.

[0006] This invention can be achieved through the following technical solutions: This invention discloses a razor blade marking device, comprising a base plate, on which feeding devices are symmetrically arranged on both sides. Each feeding device includes a lead screw and a slide rod mounted on the base plate. The lead screw is driven to rotate by a feeding motor. The feeding device also includes a slide plate, through which the slide rod passes and is slidably connected. A threaded tube is fixed on the slide plate, through which the lead screw passes and is threadedly connected. A positioning rod for placing the blade is also provided on the slide plate. A support rod for cooperating with the blade is fixed above the base plate, through which the support rod passes and is slidably connected. A rotary motor is also fixed on the base plate, with a rotating seat fixed at the output end of the rotary motor. A laser marking head is fixed on the rotating seat. After stacking the blades to be marked, the blades are placed on the positioning rods by passing them through the positioning holes in the blade slots. One end of the positioning rod is fixed to the slide plate, and the bottom of the other end of the blade is supported by a support rod. The laser marking head marks one side of the outermost blade. The laser excites the working material through the pump source, creating population inversion. The laser oscillates and amplifies in the resonant cavity, generating a continuous laser beam. The laser beam acts on the blade through the laser marking head, vaporizing the material on the blade surface and forming the corresponding mark. After the blade is marked, the corresponding feed motor drives the lead screw to rotate. When the lead screw rotates, the slide plate moves, and the blade moves with the slide plate. After the outermost blade separates from the support rod... When the lead screw stops, the blades rotate around the positioning rod due to gravity. After the outermost blade rotates, the marking position on the second blade is aligned with the laser marking head. The laser marking head then marks the second blade again. This process is repeated until all blades are marked. Then, the rotary motor drives the rotating seat to rotate 180 degrees, and the laser marking head marks the blades on another feeding device again. This process is repeated. This device does not require individual blade placement. After marking one stack of blades, the laser marking head rotates to mark the blades on the other feeding device. After marking one stack of blades, the positioning rod is removed and the stacked blades are re-secured, greatly improving the marking efficiency of the blades.

[0007] Preferably, a nozzle is also provided above the support rod. After the marked blade separates from the support rod, the air pump sprays compressed gas through the nozzle, which sprays between two adjacent blades to separate them. After separation, the marked blade rotates around the corresponding positioning rod.

[0008] Preferably, a support plate is also fixed on the slide plate, and a fixing plate is also fixed on the slide plate above the support plate. A screw is provided on the fixing plate and rotatably connected to it. A pressure plate is also provided below the fixing plate, and a threaded block is fixed on the pressure plate. The screw is threadedly connected to the threaded block. Each slide plate has a positioning groove, and each pressure plate has a positioning block fixed to it. The positioning block is slidably connected to the positioning groove. The positioning rod passes through the slide plate and is slidably connected to it. When fixing the positioning rod of the stacked blades, the positioning rod passes through the slide plate, with one end reaching between the support plate and the pressure plate. The screw is rotated; as the screw rotates, the threaded block descends, the pressure plate descends, and the pressure plate presses the positioning rod onto the support plate, fixing the positioning rod. After the positioning rod is fixed, each blade is rotated to make it horizontal, and the blade ends are placed on the support rod.

[0009] Compared with existing technologies, the present invention has the following advantages: This device eliminates the need to individually place each blade. After marking a stack of blades, the laser marking head rotates to mark the blades on the other side of the feeding device. After marking a stack of blades, the positioning rod is removed and the stacked blades are fixed again, greatly improving the marking efficiency of the blades. Attached Figure Description

[0011] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings: Example

[0012] like Figures 1 to 2As shown, this embodiment discloses a razor blade marking device, including a base plate 1. Feeding devices 2 are symmetrically arranged on both sides of the base plate 1. The feeding devices 2 include a lead screw 6 and a slide rod 3 arranged on the base plate 1. The lead screw 6 is driven to rotate by a feeding motor 7. The feeding devices 2 also include a slide plate 4. The slide rod 3 passes through the slide plate 4 and is slidably connected to the slide plate 4. A threaded tube 5 is also fixed on the slide plate 4. The lead screw 6 passes through the threaded tube 5 and is threadedly connected to the threaded tube 5. A positioning rod 15 for placing the blade 9 is also provided on the slide plate 4. A support rod 8 for cooperating with the blade 9 is also fixed above the base plate 1. The support rod 8 passes through the slide plate 4 and is slidably connected to the slide plate 4. A rotary motor 11 is also fixed on the base plate 1. A rotary seat 12 is fixed at the output end of the rotary motor 11. A laser marking head 13 is fixed on the rotary seat 12. After stacking the blades 9 to be marked, the blades 9 are stacked on the positioning rod 15 after passing through the positioning holes 10 on the through slots of each blade 9. One end of the positioning rod 15 is fixed to the slide plate 4, and the bottom of the other end of the blade 9 is supported by the support rod 8. The laser marking head 13 performs marking on one side of the outermost blade 9. The laser excites the working substance through the pump source, forming a population inversion, which oscillates and amplifies in the resonant cavity to generate a continuous laser beam. The laser beam acts on the blade 9 through the laser marking head 13, vaporizing the surface material of the blade 9 and forming the corresponding mark on the surface of the blade 9. After the blade 9 is marked, the corresponding feeding motor 7 drives the lead screw 6 to rotate. When the lead screw 6 rotates, the slide plate 4 moves, and the blade 9 moves with the slide plate 4. After the outermost blade 9 separates from the support rod 8, the lead screw 6 rotates. When rod 6 stops, the blades 9 rotate around positioning rod 15 due to gravity. After the outermost blade 9 rotates, the marking position on the second blade 9 is aligned with the laser marking head 13. The laser marking head 13 then marks the second blade 9 again. This process is repeated until all blades 9 are marked. Then, the rotary motor 11 drives the rotary seat 12 to rotate 180 degrees. The laser marking head 13 then marks the blades 9 on another feeding device 2 again. This process is repeated. This device does not require individual placement of blades 9. After marking one stack of blades 9, the laser marking head 13 rotates to mark the blades 9 on the other feeding device 2. After marking one stack of blades 9, positioning rod 15 is removed and the stacked blades 9 are fixed in place again. This greatly improves the marking efficiency of the blades 9.

[0013] Among them, a support plate 16 is fixed on the slide plate 4, and a fixing plate 19 is fixed on the slide plate 4 above the support plate 16. A screw 20 is provided on the fixing plate 19 and is rotatably connected to the fixing plate 19. A pressure plate 18 is provided below the fixing plate 19. A threaded block 21 is fixed on the pressure plate 18. The screw 20 is threadedly connected to the threaded block 21. A positioning groove 17 is provided on the slide plate 4. A positioning block 22 is fixed on the pressure plate 18. The positioning block 22 is slidably connected to the positioning groove 17. A positioning rod 15 passes through the slide plate 4 and is slidably connected to the slide plate 4. When the positioning rod 15 of the stacked blades 9 is fixed, the positioning rod is passed through the slide plate 4, and one end of the positioning rod 15 reaches between the support plate 16 and the pressure plate 18. The screw 20 is rotated. When the screw 20 rotates, the threaded block 21 descends and the pressure plate 18 descends. The pressure plate 18 presses the positioning rod 15 onto the support plate 16 to fix the positioning rod 15. After the positioning rod 15 is fixed, rotate each blade 9 to make the blade 9 horizontal and place the end of the blade 9 on the support rod 8. Example

[0014] This embodiment discloses a razor blade marking device. Based on the structure and principle of Embodiment 1, this embodiment also provides a nozzle 14 above the support rod 8. After the marked blade 9 separates from the support rod 8, the air pump sprays compressed gas through the nozzle 14. The nozzle 14 sprays gas between two adjacent blades 9, separating the blades 9. After separation, the marked blade 9 rotates around the corresponding positioning rod 15.

[0015] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
